List of Puerto Rican Military Personnel - World War I

World War I

In World War I Puerto Ricans opened fire, in what is considered to be the first shot of that war on behalf of the United States, on an armed German supply ship trying to force its way out of San Juan Bay. As members of the "Porto Rico Regiment" they were sent to Panama to guard and defend the Panama Canal Zone. In New York, many Puerto Ricans of African descent joined the 396th Infantry Regiment which was mostly composed of African Americans. As members of the 396th Infantry Regiment, also known as the "Harlem Hellfighters," they were not allowed to fight alongside their white counterparts; however, they were permitted to fight as members of a French unit in French uniforms and were awarded the French Croix de guerre. Before the United States entered World War II, Puerto Ricans were already fighting on European soil, not only in the Rif War, but also on both sides of the Spanish Civil War.
